4.2 Turning the system ON/OFF
A single press on the POWER button switches the system ON,
and the following start up information is shown on the display:
Once installed, calibrated and started, the HS50 needs no
manual intervention during operation.
After power on, up to 15 minutes is needed to obtain full
accuracy on all data. Since there normally is no reason for
turning the unit off, it should be left running continuously.
The HS50 will be shut down in a controlled way when the
POWER button is pressed for 1-2 seconds. Then the message
Shutdown in process will appear on the screen. If the
POWER
button is pressed and held for 5 seconds or more, the system is
shut down immediately. Typically used if the system has a hang-
up and does not respond on any commands. The configuration
of HS50 is however stored on the internal flash disk independent
on how the unit is powered off.
4.3 Performance monitoring

side of the screen data quality and status information. The
indicators are as follows:
• HDT-Q. The quality of the heading measurements. Two
black bar graphs indicate normal accuracy, one black and one
white bar graph indicate reduced accuracy and two white
invalid heading.
